Subject: [PATCH 04/16] ngircd: Do PING-PONG on server burst to "sync servers"
|
|
|
|
Imagine we had three servers, A, B & C linked like so: A<->B<->C:
|
|
|
|
If Anope is linked to A and B splits from A and then reconnects B
|
|
introduces itself, introduces C, sends EOS for C, introduces B's clients
|
|
introduces C's clients, sends EOS for B. This causes all of C's clients
|
|
to be introduced with their server "not syncing".
|
|
|
|
We now send a PING immediately when receiving a new server and then
|
|
finish sync once we get a pong back from that server.
